π Wife Acceptance Factor
Wife acceptance factor, wife approval factor, or wife appeal factor (WAF) is an assessment of design elements that either increase or diminish the likelihood a wife will approve the purchase of expensive consumer electronics products such as high-fidelity loudspeakers, home theater systems and personal computers. Stylish, compact forms and appealing colors are commonly considered to have a high WAF. The term is a tongue-in-cheek play on electronics jargon such as "form factor" and "power factor" and derives from the idea that men are predisposed to appreciate gadgetry and performance criteria whereas women must be wooed by visual and aesthetic factors.

π The Unreality of Time
"The Unreality of Time" is the best-known philosophical work of the Cambridge idealist J.Β M.Β E. McTaggart (1866β1925). In the argument, first published as a journal article in Mind in 1908, McTaggart argues that time is unreal because our descriptions of time are either contradictory, circular, or insufficient. A slightly different version of the argument appeared in 1927 as one of the chapters in the second volume of McTaggart's greatest work, The Nature of Existence.
The argument for the unreality of time is popularly treated as a stand-alone argument that does not depend on any significant metaphysical principles (e.g. as argued by C.Β D. Broad 1933 and L.Β O. Mink 1960). R.Β D. Ingthorsson disputes this, and argues that the argument can only be understood as an attempt to draw out certain consequences of the metaphysical system that McTaggart presents in the first volume of The Nature of Existence (Ingthorsson 1998 & 2016).
It is helpful to consider the argument as consisting of three parts. In the first part, McTaggart offers a phenomenological analysis of the appearance of time, in terms of the now famous A- and B-series (see below for detail). In the second part, he argues that a conception of time as only forming a B-series but not an A-series is an inadequate conception of time because the B-series does not contain any notion of change. The A-series, on the other hand, appears to contain change and is thus more likely to be an adequate conception of time. In the third and final part, he argues that the conception of time forming an A-series is contradictory and thus nothing can be like an A-series. Since the A- and the B- series exhaust possible conceptions of how reality can be temporal, and neither is adequate, the conclusion McTaggart reaches is that reality is not temporal at all.

π YIMBY Movement
The YIMBY movement (short for "yes in my back yard") is a pro-infrastructure development movement mostly focusing on public housing policy, real estate development, public transportation, and pedestrian safety in transportation planning, in contrast and in opposition to the NIMBY ("not in my back yard") movement that generally opposes most forms of urban development in order to maintain the status quo. As a popular organized movement in the United States, it began in the San Francisco Bay Area in the 2010s amid a major housing affordability crisis and has subsequently become a potent political force in state and local politics across the United States.
The YIMBY position supports increasing the supply of housing within cities where housing costs have escalated to unaffordable levels. They have also supported infrastructure development projects like improving housing development (especially for affordable housing or trailer parks), high-speed rail lines, homeless shelters, day cares, schools, universities and colleges, bike lanes, and transportation planning that promotes pedestrian safety infrastructure. YIMBYs often seek rezoning that would allow denser housing to be produced or the repurposing of obsolete buildings, such as shopping malls, into housing. Some YIMBYs have also supported public-interest projects like clean energy or alternative transport.
The YIMBY movement has supporters across the political spectrum, including left-leaning adherents who believe housing production is a social justice issue, free-market libertarian proponents who think the supply of housing should not be regulated by the government, and environmentalists who believe land use reform will slow down exurban development into natural areas. YIMBYs argue cities can be made increasingly affordable and accessible by building more infill housing,:β1β and that greenhouse gas emissions will be reduced by denser cities.
π Demon Core
The demon core was a spherical 6.2-kilogram (14Β lb) subcritical mass of plutonium 89 millimetres (3.5Β in) in diameter, that was involved in two criticality accidents, on August 21, 1945 and May 21, 1946. The core was intended for use in a third nuclear weapon, but remained in use for testing after Japan's surrender. It was designed with a small safety margin to ensure a successful explosion of the bomb. The device briefly went supercritical when it was accidentally placed in supercritical configurations during two separate experiments intended to guarantee the core was indeed close to the critical point. The incidents happened at the Los Alamos Laboratory in 1945 and 1946, both resulting in the acute radiation poisoning and subsequent deaths of scientists: Harry Daghlian and Louis Slotin. After these incidents the spherical plutonium core was referred to as the "demon core".

π Learned helplessness
Learned helplessness is behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused from the subject's acceptance of their powerlessness: discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented. Upon exhibiting such behavior, the subject was said to have acquired learned helplessness. Over the past few decades, neuroscience has provided insight into learned helplessness and shown that the original theory actually had it backwards: the brain's default state is to assume that control is not present, and the presence of "helpfulness" is what is actually learned.
In humans, learned helplessness is related to the concept of self-efficacy; the individual's belief in their innate ability to achieve goals. Learned helplessness theory is the view that clinical depression and related mental illnesses may result from such real or perceived absence of control over the outcome of a situation.

π Greater Fool Theory
In finance, the greater fool theory suggests that one can sometimes make money through the purchase of overvalued assetsβββitems with a purchase price drastically exceeding the intrinsic valueβββif those assets can later be resold at an even higher price.
In this context, one "fool" might pay for an overpriced asset, on the assumption that he can probably sell it to an even "greater fool" and make a profit. This only works as long as there are new "greater fools" willing to pay higher and higher prices for the asset. Eventually, investors can no longer deny that the price is out of touch with reality, at which point a sell-off can cause the price to drop significantly until it is closer to its fair value.

π Namecoin
Namecoin (Symbol: β or NMC) is a cryptocurrency originally forked from bitcoin software. It is based on the code of bitcoin and uses the same proof-of-work algorithm. Like bitcoin, it is limited to 21 million coins.
Namecoin can store data within its own blockchain transaction database. The original proposal for Namecoin called for Namecoin to insert data into bitcoin's blockchain directly. Anticipating scaling difficulties with this approach, a shared proof-of-work (POW) system was proposed to secure new cryptocurrencies with different use cases.
Namecoin's flagship use case is the censorship-resistant top level domain .bit, which is functionally similar to .com or .net domains but is independent of ICANN, the main governing body for domain names.

π Posttraumatic Embitterment Disorder
Posttraumatic Embitterment Disorder (PTED) is defined as a pathological reaction to a negative life event, which those affected experienced as a grave insult, humiliation, betrayal, or injustice. Prevalent emotions of PTED are embitterment, anger, fury, and hatred, especially against the triggering stressor, often accompanied by fantasies of revenge. The disorder commences immediately and without time delay at the moment of the triggering event. If left untreated, the prognosis of PTED presents as rather unfavorable, since patients find themselves trapped in a vicious circle of strong negative emotions constantly intensifying one another and eventually leading into a self-destructive downward spiral. People affected by PTED are more likely to put fantasies of revenge into action, making them a serious threat to the stressor.
The concept of PTED as a distinct clinical disorder has been first described by the German psychiatrist and psychologist Michael Linden in 2003, who remains its most involved researcher. Even though it has been backed up by empirical research in the past years, it remains disputed as to whether embitterment should be included among psychological disorders. Therefore, PTED currently does not hold its own category in the ICD-10 but is categorized under F43.8 βOther reactions to severe stressβ. It cannot be categorized as an adjustment disorder under F43.2, since βordinaryβ adjustment disorders normally subside within six months, while PTED is much more likely to become chronical and last for much longer. A condition similar to PTED has already been described by Emil Kraepelin as early as 1915 by the name querulous paranoia as a form of traumatic neuroses, explicitly demarcating it from personality disorders.

π The Diolkos: an ancient Greek paved trackway enabling boats to be moved overland
The Diolkos (ΞίολκοΟ, from the Greek διά, dia "across" and α½Ξ»ΞΊΟΟ, holkos "portage machine") was a paved trackway near Corinth in Ancient Greece which enabled boats to be moved overland across the Isthmus of Corinth. The shortcut allowed ancient vessels to avoid the long and dangerous circumnavigation of the Peloponnese peninsula. The phrase "as fast as a Corinthian", penned by the comic playwright Aristophanes, indicates that the trackway was common knowledge and had acquired a reputation for swiftness.
The main function of the Diolkos was the transfer of goods, although in times of war it also became a preferred means of speeding up naval campaigns. The 6Β km (3.7Β mi) to 8.5Β km (5.3Β mi) long roadway was a rudimentary form of railway, and operated from c. 600Β BC until the middle of the 1st centuryΒ AD. The scale on which the Diolkos combined the two principles of the railway and the overland transport of ships remained unique in antiquity.
